●Natural explanations for observable events developed by use of the scientific method
3. Test Hypothesis

Diversity and Classification of Organism:
oProkaryotic vs. Eukaryotic
▪Prokaryotic: lack nucleus, other organelles, small (1-10 micrometers)
▪Eukaryotic: DNA packaged in nucleus, possess other organelles such as
mitochondria. Large (10-100 micrometers)
oAerobic vs. Anaerobic metabolism
▪Aerobic: cells require oxygen to break down compounds and produce
▪Anaerobic: cells break down compounds and produce energy in the
absence of oxygen
oAutotrophic vs. Heterotrophic feeding
▪Autotrophic: produce energy from chemical energy source, primarily by
▪Heterotrophic: produce energy from autotrophic organisms
